<h1 id="eugenia-nodes-with-images-defined-at-run-time">Eugenia: Nodes with images defined at run-time<a class="headerlink" href="#eugenia-nodes-with-images-defined-at-run-time" title="Permanent link">&para;</a></h1>
<p>This recipe addresses the case where the end-user needs to set an image for each node at runtime (based on Thomas Beyer's solution presented in the GMF newsgroup). For our example, we'll use the Component class.</p>
<h2 id="create-an-attribute-to-store-the-image-path">Create an attribute to store the image path<a class="headerlink" href="#create-an-attribute-to-store-the-image-path" title="Permanent link">&para;</a></h2>
<p>First we need to create an <code>imagePath</code> attribute that will store the path of the image for each component.</p>
<h2 id="set-the-figure-of-component-to-a-custom-componentfigure">Set the figure of Component to a custom ComponentFigure<a class="headerlink" href="#set-the-figure-of-component-to-a-custom-componentfigure" title="Permanent link">&para;</a></h2>
<p>The next step is to set the figure of Component in Eugenia to a custom figure. After those two steps, our definition of Component looks like this:</p>
<pre class="prettyprint lang-emf"><code>@gmf.node(label="name", figure="ccdl.diagram.figures.ComponentFigure", label.placement="external")
class Component {
  attr String name;
  attr String imagePath;
}</code></pre>
<p>Once we generate the diagram code, we'll get an error because <code>ComponentFigure</code> has not been found. We need to create the <code>ComponentFigure</code> class and set its code to the following:</p>
